This example shows how to create a transformation mapping and add it to a descriptor using Java code.

Transformation Mapping

public void customize(ClassDescriptor descriptor) { 
    TransformationMapping mapping = new TransformationMapping();  

    // configure mapping
    ... 

    // add mapping to descriptor
    descriptor.addMapping(mapping);
}
